oracle触发器 ORA-01722:invalid number 解决方法

问题在于，远程库是nvarchar2类型，本地是number类型，同步的时候有问题。

create or replace trigger tri_org_department
after insert or update
on bjlt.sys_org
for each row
  
declare
   v_uuid varchar2(36);
   v_id varchar2(36);
  
begin
  v_uuid:=sys_guid();
  v_id:=:new.ID;
    if inserting then
      insert into KEYMS.KEY_DEPARTMENT@TOBSMS_BETTERY_LOCAL.REGRESS.RDBMS.DEV.US.ORACLE.COM(depid,depcode,depname,parentid)
      values(:new.ID,:new.RESERVE4,:new.NAME,:new.P_ID);
      insert into KEYMS.KEY_USER@TOBSMS_BETTERY_LOCAL.REGRESS.RDBMS.DEV.US.ORACLE.COM(userid,username,password,truename,mobile,depid,isuse,issys,isproject)
       values(v_uuid,:new.RESERVE4,:new.RESERVE4,:new.NAME,:new.RESERVE4,:new.ID,1,1,0);
       
       insert into KEYMS.KEY_USERROLE@TOBSMS_BETTERY_LOCAL.REGRESS.RDBMS.DEV.US.ORACLE.COM(USERID,ROLEID) values(v_uuid,'0002');
    end if;
    
    if updating then
     update KEYMS.KEY_DEPARTMENT@TOBSMS_BETTERY_LOCAL.REGRESS.RDBMS.DEV.US.ORACLE.COM
    set depcode = :new.RESERVE4,
      depname = :new.NAME,
      parentid = :new.P_ID
    where depid = v_id;
    end if;
